The method is a sequence of advancing a core, constructed from pre-formed expanded polystyrene (EPS), in a straight horizontal plane through a coating chamber with constraining devices preventing lateral and vertical movement. The coating chamber is filled with a 'thick liquid stucco or plaster or cement-like mixture and imparts a layer of the liquid onto the preformed core. The thickness of the coating is controlled with templates having an opening correspondingly larger than the core size and with the desired profile. The apparatus can be configured to coat a portion of an elongate surface in the case of producing a starter strip. In the case of a decorative moulding, the coating application can be limited to the exposed decorative surfaces only. The templates are designed to be interchangeable with other coating apparatus to produce starter strips, decorative mouldings, wall panel sections and columns commonly used in the construction industry.

Title: Probe correction for gene expression level detection
Inventor: WANG XUN
IPC: G16B25/20
Filed: 2003-01-17
Abstract: Individual probes on micro-arrays are re-scaled and corrected with a set of probe dependent coefficients derived from genomic-DNA hybridization signals. A dynamic range for gDNA binding is determined by measuring a concentration signal curve. Signals for each probe are measured during multiple hybridizations within a linear range. Concentration insensitive probes are then found for two sets of experiments. Probes are discarded based on a threshold compared to their standard deviation divided by their average in each set. The correction coefficients are used to calculate a corrected intensity for each probe. Probes having high uncertainty (0.5 in one embodiment) are discarded. A weighting factor for each probe is determined along with an uncertainty factor. Finally, a call for each gene is made, such as absent, marginal or present.
